Block's Quantum Cascade Laser-based products are used in a variety of applications — including chemical threat detection, speciation of natural gas, hydrocarbon analysis, fugitive emissions detection, and process monitoring in manufacturing.
The real-time gas, liquid, and surface analysis abilities of Block's spectroscopy products allows for rapid detection of specific chemicals and substances. Unlike traditional Mass Spectroscopy, HPLC, or Raman solutions, Block's award-winning Quantum Cascade Laser-based products allow for non-destructive, eye-safe analysis.
Following is a brief list of industrial applications in which Block's quantum cascade products provide significant value over traditional methods.
- Real Time Measurement of BTU, Calorific Value, and Wobbe Index Including Hydrocarbon Speciation: Block Engineering's LaserSense-CV provides precise, continuous measurement of CV, BTU, and Wobbe Index. In this application note, we detail the differences between Gas Chromatography, Mass Spectrometry, and Quantum Cascade Laser techniques in the full analysis of natural gas.
- Open Path Detection of Acrolein Leaks: In this application note, we detail the capabilities of Block's open path LaserWarn system to detect levels of Acrolein at concentrations of around 1 ppm.
- Detection of Chemical Threats: Block has developed an open-path chemical detection system that detects chemical threats — including Toxic Industrial Chemicals and Materials (TICs/TIMs) and Chemical Warfare Agents (CWAs) — in parts-per-billion (ppb) ranges from standoff distances of hundreds of meters. The system registers warnings in seconds, allowing for rapid response to threats.
- Gas Leak Detection and Fenceline/Perimeter Monitoring: Block Engineering's LaserWarn detects target chemicals, including Volatile Organic Compounds (VOCs), across perimeters as large as 500 meters. The eye-safe lasers allow for mounting in areas where workers or other people will be present. The system continually scans for gases that cross the laser beam path, and triggers alarms when concentration thresholds are detected.
